The spectacle frames consist of a lightweight and flexible frame made of extremely robust, rustproof and hypoallergenic spring steel wire (1 mm). Different physiognomies can be taken into account individually when bending the frame. The elliptical polished, unbreakable lenses are given the notches and steps for fastening in the spectacle frames on the milling attachment and can be inserted in no time. Heat-shrinkable sleeves made of hypoallergenic plastic on the ear piece ends increase the wearing comfort of the glasses. Because the glasses have very little weight, they do not require nosebridges. Two coloured glass pearls give each pair of glasses its own personal design.
